Soil pH, Fundamental ??
I think that soil chemistry plays a vital role in the state of health of our garden. It is , of course, is not that easy for us to figure things all out, unless we keep sending samples to soil labs.
But there is one essential test that we all can do and that is pH test. I have been using these Now, I have heard that many say : Those gadgets are not accurate . but to me they give provide some ball park figures to go buy. AND you might be able to adjust what those devices tell you.
All you have to do is find something that you know its pH is. Say. household vinegar(4.5% acidity) has a pH of 2.2. Distilled water has a pH of almost 7. So by making a solution of vinegar and distilled water, you can make a test solution(say pH =5). Now use your device to measure it and see how far off is it. Then adjust your soil test measurements accordingly.
I want to know if there is someone here who has done this and know how it can be done practically.
